Description

Technical Field

[0001] This utility model relates to the field of hair clipper technology, specifically to a hair clipper fixed blade. Background Technology

[0002] A hair clipper is an electric tool specifically designed for trimming hair. It helps people maintain a neat hairstyle, remove excess long hair and stray hairs, and create a clearer, more defined silhouette, thereby enhancing overall appearance and confidence. A well-chosen hairstyle typically makes a good first impression and helps project a better image in the workplace and social settings.

[0003] During operation, the hair clipper relies on the high-speed reciprocating motion of its internal moving and stationary blades to achieve its cutting function. However, this high-intensity friction also brings some problems during use: under prolonged continuous use, the blades can generate excessive heat due to continuous friction, and the operating noise will also increase significantly; this not only affects the smoothness of the blade assembly's movement but also reduces the precision and stability of hair cutting, ultimately negatively impacting the user's hair-cutting experience. In addition, the current common design of stationary blades also has certain flaws: cut hair clippings easily enter the blade gaps or remain in the internal corners, making them difficult to clean thoroughly; accumulated hair clippings not only pose hygiene risks and breed bacteria but may also hinder the normal movement of the blades, causing jamming, pulling, and even accelerating blade wear, shortening the overall lifespan of the product.

[0004] Therefore, how to design a clipper blade that can effectively reduce friction and is easy to clean is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0006] Therefore, this utility model provides a hair clipper blade, comprising: The blade body includes a mounting component and a blade head integrally formed at the front end of the mounting component, wherein the axis of the blade head forms an angle of 130°-140° with the axis of the mounting component; The mounting component has at least two protrusions formed on its top surface. The protrusions are used to make frictional contact with the tail end of the moving blade, and their lateral width is greater than the movement displacement of the moving blade. At least one first oil reservoir is formed on the top surface. The blade head is used to cooperate with the tip of the moving blade to cut hair, and a plurality of second oil reservoirs are formed on the top surface.

[0007] As a preferred embodiment, the front end of the mounting component is formed with a limiting baffle, which is located between the mounting component and the cutting head.

[0008] As a preferred embodiment, chip discharge ports are formed on both sides of the cutter head facing the mounting component.

[0009] As a preferred embodiment, the top surface of the boss is formed with three first oil storage tanks of different sizes; And / or, the boss is formed with three elongated openings of different sizes.

[0010] As a preferred embodiment, the cutter head includes a comb-tooth portion and a bent portion integrally formed on the comb-tooth portion, the bent portion being located between the comb-tooth portion and the mounting member; the axis of the comb-tooth portion and the axis of the bent portion form an angle of 200°-210°.

[0011] As a preferred embodiment, the comb tooth portion has a plurality of comb teeth, each of which has a cutting edge formed on both sides, and the axis of the cutting edge forms an angle of 60°-80° with the axis of the comb tooth; the free end of the comb tooth has a protrusion formed.

[0027] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0028] This embodiment provides a fixed blade for a hair clipper, such as... Figure 1-4 As shown, it includes: a blade body 1; wherein, the blade body 1 includes a mounting part 2 and a cutting head 3 integrally formed at the front end of the mounting part 2, the axis of the cutting head 3 forming an angle of 130°-140° with the axis of the mounting part 2; at least two bosses 4 are formed on the top surface of the mounting part 2, the bosses 4 are used for frictional contact with the tail end of the moving blade, and the lateral width is greater than the movement displacement of the moving blade, and at least one first oil reservoir 41 is formed on the top surface; the cutting head 3 is used to cooperate with the head end of the moving blade to cut hair, and several second oil reservoirs 31 are formed on the top surface.

[0029] When using the fixed blade of the hair clipper in this embodiment, the blade body 1 is installed on the hair clipper, so that it cooperates with the moving blade to form a cutting head. Lubricating grease (such as molybdenum disulfide grease, polytetrafluoroethylene grease, etc., which are usually in paste or grease form and can adhere to the metal surface for a long time, continuously providing lubrication) is injected into the first oil reservoir 41 and the second oil reservoir 31. In this embodiment, the fixed blade of the hair clipper, by injecting lubricating grease into the oil reservoir, can form a continuous lubricating film between the moving blade and the blade body 1, effectively reducing the coefficient of friction, suppressing temperature rise and noise caused by high-speed reciprocating motion, thereby ensuring smooth operation and precise cutting of the cutting head assembly, and improving the overall stability and comfort of use.

[0030] like Figure 2 As shown, the front end of the mounting component 2 is formed with a limiting baffle 21. The limiting baffle 21 is located between the mounting component 2 and the blade head 3, and is used to prevent hair clippings from entering the interior of the mounting component 2. Through the isolation effect of the limiting baffle 21, the amount of hair clippings entering the mounting component 2 can be reduced; this not only helps to maintain cleanliness, improve hygiene, and reduce the risk of bacterial growth, but more importantly, it can ensure the smooth meshing movement between the moving blade and the blade body 1, avoiding problems such as jamming and hair pulling caused by hair clippings, thereby helping to maintain cutting accuracy, reduce abnormal wear, and ultimately extend the service life of the entire hair clipper.

[0031] like Figure 3 As shown, the blade head 3 has two flanks 32 formed on both sides of the end facing the mounting member 2, which are suitable for discharging hair clippings from inside the blade head 3. The flanks 32 can promptly discharge hair clippings generated during the haircutting process, preventing clippings from accumulating and causing blockages.

[0032] The top surface of the boss 4 is formed with three first oil storage grooves 41 of different sizes. The presence of three first oil storage grooves 41 can increase the storage capacity of grease, which helps to form a more stable lubricating film between the moving blade and the blade body 1, significantly reducing the coefficient of friction and improving the smoothness of operation. The boss 4 is formed with three elongated openings 42 of different sizes. The function of the elongated openings 42 is to reduce the weight of the blade body 1 and save material.

[0033] The blade head 3 includes a comb-tooth portion 5 and a bent portion 6 integrally formed on the comb-tooth portion 5. The bent portion 6 is located between the comb-tooth portion 5 and the mounting member 2. The axis of the comb-tooth portion 5 and the axis of the bent portion 6 form an angle of 200°-210°. This structural design allows for a larger cleaning space between the blade body 1 and the moving blade, thus facilitating the cleaning and rinsing of hair.

[0034] The comb tooth 5 has a plurality of comb teeth 51, and each comb tooth 51 has a cutting edge 52 formed on both sides. The axis of the cutting edge 52 forms an angle of 60°-80° with the axis of the comb tooth 51. The free end of the comb tooth 51 has a protrusion 53 formed, which serves to provide safety protection, stable guidance and improve comfort.

[0035] The top surface of the bending part 6 is uniformly formed with a plurality of first guide grooves 61. The first guide grooves 61 are used to guide the hair fragments and help the hair fragments to be discharged smoothly.

[0036] The mounting component 2 has two mounting through holes 22 formed on it. A mounting cylinder 23 is formed on the middle of the same side of the two mounting through holes 22, away from the mounting through holes 22. The mounting through holes 22 and the mounting cylinder 23 are mounting structures used to mount the blade body 1 to the hair clipper.

[0037] The top surface of the mounting component 2 is formed with a plurality of reinforcing ribs 24, which are used to enhance the structural rigidity of the mounting component 2.

[0038] like Figure 4 As shown, several second guide grooves 11 are uniformly formed on the bottom surface of the blade body 1. The second guide grooves 11 are used to guide the hair into the cutting area to ensure that the hair can be smoothly and accurately cut by the passive blade engaging with the blade body 1, thereby improving the efficiency and neatness of hair cutting.

[0039] The fixed blade of the hair clipper in this embodiment is used as follows: During use, the blade body 1 is installed on the hair clipper, allowing it to cooperate with the moving blade to form a cutting head. Lubricating grease is injected into the first oil reservoir 41 and the second oil reservoir 31. When the moving blade performs high-speed reciprocating motion, its head and tail ends respectively come into frictional contact with the blade head 3 and the boss 4. The lubricating grease effectively reduces the coefficient of friction, suppressing temperature rise and noise caused by high-speed reciprocating motion, thereby ensuring smooth operation and precise cutting of the blade head assembly, and improving overall stability and comfort. Hair clippings generated during cutting are discharged through the chip removal port 32, while excess hair clippings are blocked by the limiting baffle 21 to reduce the likelihood of them entering the mounting component 2.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
